Is this new technology cool or creepy?

1 / 19

Back to Gallery

There’s a gadget for everything. Want to follow your kids digitally? There’s an app for that. Do you need a smart bra to sense when you’re in love? Ravijour has you covered.

There are obvious and often very cool applications for devices like Google Glass, wearable cameras and smart clothing. But using them daily can come with a cost: our privacy. How would you feel if someone around you wore a camera that took a picture every 30 seconds? What if one of your friends wore a wristband that constantly recorded the previous 60 seconds? Me, I would think twice or three times about everything I said.

The above devices triggered our creep-dar. Most of them have very real, practical uses, but seem more than a little invasive. Let us know what you think below.
